To all whom it may concern:'

Be it known that 1, Isaac J D. -FAIR- nUnsT, a citizen of the United States, resid-' mg atsOrfordville, in

the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in Covers for Pneumatic Tires; and I do declare the following to be a full, clear, and exact description of the nvention,- such as will enable others skilled in the "art to which it appertains, to

" make and use the same.

This invention is an improved cover and armor for the pneumatic tire of an automobile or other vehicle wheel and it consists in the construction, combination and arrangement of devlces hereinafter described and claimed. v

having my improved armoredf cover; ,and

same on a larger scale.

ro vide a cover 1 for the outer tire d,.w ich cover is preferably made of rawhide or may be made of any other suitable tough, elastic material. that it covers the entire outer surface of the outer tire cl and its edges 2 bear on the flanges c of the outer tire and are clamped between said flanges and the flanges b of the wheel when the tire is fitted on the wheel, so that the said ed es 2 are covered and concealed by the said flanges l) of the, wheel rim. The said cover 1 is e'rmanently secured near itssaid ed es 2 to the outer tire I). For this purpose, employ iivets 3', ofwhich a suitable number are used, the said rivets being suitably spaced apart' The said rivets extend outwardly through the tire d,near its edges, and through the cover 1 at a suitable distance from the edges of said cover, and under the headsl i of the said rivets, I lace washers 5, which are preferably of qua' ran heads ofthe rivets from tearing1 to project outwardly gular form and are made preferably of raw- .iide or other suitable tong strong and elas- The said washers prevent. the or otherwise injuring the outer tire d, and ey also serve beyond the edges of the tie material.

The said reinforcingstrip is secured to the cover 1 means of rows-of b rivets 8, which rivets are disposed in annular i circumferential series exten' periphery of the wheel-formed b the said cover 1 and a suitable number oft e said annular series of rivets are employed according. to the size of the tire and of thecover. The heads 9 of the rivets are embedded in the innor surface of the reinforcing strip 6. The shanks of the rivets extend through the outer cover 1 and project outwardly from said cover. Armor platesor washers 10 are placed on the shanks of the 'rivets and bear against the 'outer surface of the cover 1- Reinforcing anti-skidding washers 11 are placed on the said shanks and bear against the outer surfaces of said armorlwashers and the projectin outer ends of the rivet shanks are arset to form shoul ers tia ly headed or) up the said reinforcing washers 11 and hence also the armor washers in place. The partially headed'rivets also form anti-slippingprojections.

The number of the rivets, the spaces between them and the size of the armor washers are such that the armor washers cover nearly all of the tread surface of the cover 1 and hence constitute an armor which effectually prevents the cover and'the tire from being punctured.
